I keep running into a SIGABRT error with the message 

"2017-04-20 17:37:54.872 SepsisHub[3670:1670129] Unknown class _TtC10Sepsis_Hub14ViewController in Interface Builder file.
2017-04-20 17:38:54.903 SepsisHub[3670:1670129] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UIViewController 0x7fcb8ae03240> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key FirstHour.'"

however, I cannot find a connection that is missing in either the storyboard or .swift file. There are no error messages when building, and it seems like for some reason the program cant find the IBOutlet and I don't understand why considering I've deleted them all and reconnected multiple times in both the swift file and the storyboard connector with no change.

Thank you for any assistance. Further screenshots will be provided if needed.

  • in xib/storyboard, right click on your `Files Owner` / `ViewController` to see the list of outlets. check for any outlet that does not exist in your class. – janusfidel Apr 20 '17 at 21:53

In your xib/storyboard, right click on your Files Owner / ViewController to see the list of outlets. check for any outlet that does not exist in your class. This could happen when you connected an IBOutlet then removed or renamed the property. Example below shows an IBOutlet named labelIDeleted shows warning because I removed the property from my class

EDIT:

Also check if your ViewController is assigned correct class. enter image description here
